Abstract
All nonlinear loads cause some levels of harmonic distortions in electric power system and thus becoming power quality problems. While harmonics have other origins such as arc devices, the non-linear source is becoming more prominent due to the proliferation of electronics devices. This paper examines the harmonic at the distribution end of the power network with the aim of proffering a solution. It is to design and simulate a passive harmonic filter to mitigate the effect of the harmonics. The simulated model is to be validated with experimental field measurement of harmonics. The study was carried out at the Information and Communication Centre (ICT) section of the Federal Polytechnic Ilaro using Harmonic Estimator and Power and Harmonics Analyser for simulation and field measurement respectively. It was established that the THD for current from both simulation (23.2%) and measurement (23.86%) are above the international standards and the limit has been violated. The measured and simulated values of the THD shows a high correlation. However, with the introduction of a passive filter, the distortion was reduced to 3.93% using simulation. The need to introduce a passive filter in any location with a high density of nonlinear loads such as ICT of tertiary Institutions for mitigating harmonic distortion becomes imperative.
